Unless stated otherwise, the spectral fitting for all XMM-Newton spectra is performed with XSPEC [1]} version: 12.10.1 using the following model,
\(\begin{split}\mathtt {Model_{XMM} =} & \quad \mathtt {constant\times (apec_1 + phabs\times (apec_2 +}\\&\quad \mathtt {powerlaw) + gauss_1 + gauss_2 + gauss_3 + }\\&\quad \mathtt { gauss_4 + gauss_5)\, + phabs\times apec_3},\\\end{split}\)
